Fact Check
The claim is strongly supported by the primary source: SpaceX's actual SEC S-1 filing (Space Exploration Technologies - S-1, SEC EDGAR), filed May 20, 2026. The Futunn article directly quotes the S-1 text confirming '18,712 units of Bitcoin with a cost basis of $661 million' as of both March 31, 2026 and December 31, 2025, which validates the Dec. 31, 2025 date stated in the claim. The Block independently corroborates the 18,712 BTC figure, $661M cost basis, and ~$35,000/BTC average acquisition price. The Odaily source further confirms all key figures. The only minor imprecision is the claim's rounding of the implied purchase price to 'roughly $35,000' when the actual figure is ~$35,300 — a negligible difference. All material facts (BTC quantity, cost basis, implied price, filing type, and balance sheet date) are confirmed.
Summary

SpaceX disclosed in its S-1 filing that it held 18,712 Bitcoin as of Dec. 31, 2025, with a total cost basis of about $661 million, or roughly $35,000 per BTC. Separate market-value reporting placed the position at about $1.45 billion, implying roughly $789 million in unrealized gains at prices above $77,000. The filing supports reports that SpaceX is seeking a public listing on Nasdaq under the ticker SPCX, which would make it one of the largest public companies to hold Bitcoin on its balance sheet. The report also states that SpaceX’s holdings rank seventh among known corporate Bitcoin holders and that future public filings would reflect Bitcoin-related valuation changes under fair-value accounting rules.
